Custom Source Header is a middleware plugin for Traefik. It injects the remote address of the client into a selectable header.
When operating a kubernetes environment inside a private network combined with a second layer of Traefik, the remote address of the client is not available to the application due to header overwriting.
To use the plugin please install it according to the following instructions from the Traefic Plugin Catalog: https://plugins.traefik.io/plugins/633a02e3eff06de33b092377/custom-source-header
